Medical database four-delta-one was a database aboard the Galaxy-class Federation starship USS Enterprise-D.

In 2368, Lieutenant Commander Geordi La Forge accessed this database and interacted with the ship's computer voice during his research for the cause of the coma into which Deanna Troi, William T. Riker, and Beverly Crusher had fallen. (TNG: "Violations")
